Literacy skills are important for children's development. The present study explored the effectiveness of a parent coaching approach on the reading and spelling skills and compared cognitive-linguistic skills performances between Chinese children with and without dyslexia. Participants were 33 children with dyslexia and 77 children without dyslexia, as well as their parent, in Hong Kong. Children were divided into three groups: dyslexia with training, non-dyslexia with training, and non-dyslexia without training. Parents in both training groups were instructed to facilitate children's literacy skills. A series of cognitive-linguistic skills were tested on children at pretest. Children received measures of character reading, word reading, and word spelling before and after the parent coaching. Results showed that, compared to children without dyslexia, children with dyslexia performed significantly more poorly on all cognitive-linguistic skills. Analyses of the training effect demonstrated that the dyslexia with training group significantly improved their performances on word reading and word spelling following the intervention. In addition, those without dyslexia who experienced training performed significantly better on character reading and word spelling at posttest than pretest. These results suggest that parent coaching can be one potentially effective method of promoting literacy skills among children both with and without dyslexia.
